Safety Precautions

Hydraulics&Pneumatic

Haunted House

the liquid in the system must be recirculated, thus requiring more maintenance, and also storage, as liquids do not compress

* have more things my toy does

*more eco- friendly materials

*find a way to make fake blood cleaner, and more efficient

*making the house stronger and more durable

*use different liquids (more viscous ones) in real life

* Ages 6+

* Toy may be too gruesome for some younger children

* fake blood leaks out (messy)

*syringes may pinch fingers

*may be difficult to push/pull syringes

About Pneumatics

the primary disadvantage of pneumatics, is that gas can be compressed, and decompressed, this is an advantage for storage, but makes control difficult

pneu·mat·ic

Toy Purpose: Halloween Decoration

adjective

1.containing or operated by air or gas under pressure.

How a Pneumatic

System Works

push on piston of Plunger A

History

What it includes:

-Door Opens

-Ghost Pop- Up

-Vampire Fly

- Leaking Blood

air is then forced up Plunger B, and the piston is then pushed up

Pros & Cons of Hydraulic

and Pneumatic

air is then compressed and is then transmitted through tubing

*first pneumatic systems were compressors seen around 3000 BC

*these were used to provide small puffs of air to aid in starting a fire

*evolved into larger, more advanced compressors

used in metal smelting about 1500 B.C

Materials Used

Pneumatic

Hydraulic

Cons

Pros

-control ability

-quieter machines

-less chemicals

-reliability

-can move heavier

loads

-takes less power

-clean (air)

-less costly to run

-availability

-maintenance

-storage use (can

be compressed)

-control ability

-noisiness

-chemicals

-durability

-safety

-cannot move

heavier loads

-small delay

-more power

-leakage

-costly to run

-availability

-maintenance

-storage use

(can't be

compressed)

Haunted House

*syringes

*tubing

*paint

*fake blood

*foam decorations

*cardboard

*black streamers

*modge podge

*glue gun& glue

*Haunted House is both hydraulic & pneumatic

*Door Opener, Ghost Pop Up are Pneumatic (gases)

*Vampire Fly, and Leaking Blood are Hydraulic (liquid)

Thanks for Watching :)

hy·drau·lics

1.

3.

noun

1.the branch of science and technology concerned with the conveyance of liquids through pipes and channels, especially as a source of mechanical force or control.

2.hydraulic systems, mechanisms, or forces.

Ghost Pop up

*push down on the syringe

and ghost comes up

*pull back on syringe and he goes down

Vampire Fly

*push down on syringe Vampire Flies out

*pull back on syringe and vampire flies back in his coffin

How a Hydraulic System Works

push on Plunger A

Leaking Blood

*push on the syringe and blood comes dripping

out the window

Door Opener

*push on syringe and door opens

*pull back on syringe and door slowly closes

fluid is then forced up Plunger B, and the

piston is then raised up

*Early uses of Hydraulics date back to Ancient Egypt

when Hydraulics were used for irrigation

*water canals from prehistoric times still exist in Egypt

*Greeks used Hydraulics to form "hydraulic wheels"

fluid is then compressed

and is transmitted through tubing

Uses Today of Hydraulics

&Pneumatics

Blaise Pascal

Pneumatics

Pascals Law

Hydraulics

*Blaise Pascal was born June 19th, 1623, in Clermont-Ferrand, France

Submitted to: Mrs. Pona

*French mathematician, physicist, inventor, writer and Christian philosopher.

*earliest work was about the study of fluids, and concepts of pressure and vacuum

n

*created "Pascals Law" (pressure equals force divided by area

* *Died August 19th, 1662 (age 39) in Paris, France

*Air brakes on buses and trucks

*exercise machines

*pipe organs

*Inflatable structures (balloons..)

*pneumatic pump

*pneumatic tires

*Pressure sensors

*vacuum cleaners

*Some nail guns

*Bicycle/ball pumps

*car breaks

*airplanes

*heavy equipment

*elevators

*wind turbines

*gasoline pumps

*amusement park rides

*dish washers

*snow plows

*bakeries

*mining

Pascal's Law

Submitted by: Emily Herod

P= pressure

F= force

A= area

Blaise Pascal

P= F

A

When using this formula, you will get the mechanical efficiency of your syringes

Submitted on: Monday, March 30th

“Pressure applied to a confined fluid at any point is transmitted undiminished throughout the fluid in all directions and acts upon every part of the confining vessel at right angles to its interior surfaces and equally upon equal areas"

~Blaise Pascal
